Co-Owner Right of Legal Redemption in the Philippines

By the CivilLaw.PH Editorial Team, led by publisher Anton Sheker.

Direct answer: When a co-owner sells his undivided share of land to an outsider, any other co-owner may step into the buyer’s place by paying the same price. This is legal redemption under Article 1620 of the Civil Code. You must exercise it within 30 days from written notice of the sale given by the selling co-owner, not the buyer. Exercise means a real tender of the price, and if the buyer refuses, a court action with the money consigned, all inside the 30 days.[1][2][7]

Key takeaways

  • The right belongs to a co-owner, so it exists only while the co-ownership subsists, and only against a sale to someone who is not already a co-owner.[1][4]
  • The 30 days run from the seller’s written notice. The buyer’s notice does not start the clock.[2]
  • Some rulings let actual knowledge start the period. Act within 30 days of learning of the sale.[7][8]
  • You pay the price the buyer actually paid, unless it is grossly excessive.[1][2]
  • A letter of intent is not redemption. Tender the full price; if refused, file suit and consign it within the period.[2][7]
  • Before partition, a co-heir’s sale of hereditary rights triggers Article 1088’s one-month right instead.[1][6]

This guide is for the co-owner who wants to buy back a share a relative sold to an outsider.

For what the seller’s deed actually transfers, see whether a co-owner can sell without the others’ consent.

Legal redemption sits in the Civil Code chapter on sales, in Book IV on obligations and contracts, while the co-owner’s power to sell his share comes from the co-ownership rules in Book II on property and ownership. The table lists the provisions that decide most cases.

AuthorityWhat it saysHow it applies here
Civil Code Art. 493[1]A co-owner may sell his ideal share without the others’ consent.You cannot stop the sale; you can redeem or seek partition.
Civil Code Art. 1619[1]Legal redemption is subrogation to a buyer on the same terms.You take the buyer’s place on the buyer’s terms.
Civil Code Art. 1620[1]A co-owner may redeem a share sold to a third person. A grossly excessive price is reduced. Several redeemers share proportionately.Applies to land the heirs or buyers already hold as co-owners.
Civil Code Art. 1623[1]30 days from the vendor’s written notice. No registration without the vendor’s affidavit of notice. Co-owners exclude adjoining owners.Sets your deadline and leaves a paper trail at the Registry of Deeds.
Civil Code Art. 1088[1][6]Co-heirs may redeem hereditary rights sold to a stranger before partition, within one month of the vendor’s written notice.Use this if the estate is not yet partitioned.

Article 1620 sets the right; Article 1623 sets the deadline and the notice that starts it. Both apply whether the share is in a house lot, farmland or a condominium unit held in common.

When the right of redemption exists

Check four conditions before you spend money on a tender. All four must be present.

RequirementWhat to checkEvidence
You are a co-ownerYour name is on the TCT, or you inherited a share that has not been dividedCertified true copy of the TCT; deed of extrajudicial settlement; PSA birth certificates proving heirship
The co-ownership still subsistsNo partition has assigned specific lots to each ownerTitle annotations; any partition deed or subdivision plan
The buyer is a third personThe buyer is not already a co-owner[4]The deed of sale; the title showing the registered co-owners
There was a sale or other onerous transferA sale, or dation in payment, of an undivided share; a donation or a mortgage does not transfer ownership for a price[1]The deed of sale or dacion

Third person means anyone who is not a co-owner. In Fernandez v. Spouses Tarun, the buyers were already co-owners, so the others could not redeem. The right exists to give a co-owner “a way out” of an unwelcome association.[4]

Inherited land before partition. If the land is still in your late parent’s name, a sibling who sells his hereditary rights to an outsider triggers Article 1088: one month from the selling heir’s written notice. Escabarte v. Heirs of Isaw requires a sale “to a stranger to the inheritance and before the partition is made.”[6] See what a buyer gets when heirs sell before the estate is settled.

A minor’s share. In Cabales v. Court of Appeals, a mother’s sale of her minor son’s share without court authority was void as to him. Another son who later accepted his part of the price ratified the sale and lost the right to redeem.[5]

The 30-day clock and written notice

The 30 days run from the vendor’s written notice because the seller knows who his co-owners are, and his notice confirms the sale is real and final. Notice from the buyer does not count.[2]

No form is prescribed; a seller’s letter or a copy of the deed from the seller works.[8] Exclude the day of receipt and include the last day, as the Court counted in Butte v. Manuel Uy & Sons.[2] The period is a condition precedent to the right, not a prescriptive period.[7]

Actual knowledge: two lines of cases

  • Strict. In Verdad v. Court of Appeals, a co-owner who knew of the sale was still entitled to written notice.[3] Rama v. Spouses Nogra (2021) held that actual knowledge starts the period only when coupled with laches.[8]
  • Relaxed. Baltazar v. Miguel (2021) treated a co-owner holding a copy of the deed as notified.[7] In Cabales and Escabarte, co-owners who knew of old sales for years could not claim the period never ran.[5][6]

Practical rule: Day zero is the day you reliably learn of the sale or get any copy of the deed. Missing written notice is your argument in reserve, not your plan.

Check the Registry of Deeds

Article 1623 bars registration unless the seller attaches an affidavit that he notified all possible redemptioners.[1] Get a certified copy of the registered deed and its attachments. An affidavit claiming notice you never received helps answer the defense that your period lapsed.

The redemption price and how to tender it

Pay the actual price, not today’s value. In Verdad, the redemptioner tendered the price in the notarized deed, and a refusal based on the lot’s higher present value did not defeat redemption.[3] If the deed understated the price for tax reasons, expect a fight over which figure controls.

Grossly excessive price. Article 1620 lets you pay only a reasonable price.[1] In Butte, one realtor’s estimate was not enough to cut a ₱500,000 price.[2] Bring zonal value, comparable sales and more than one appraisal.

Tender must be real. The tender or consignation guarantees the buyer that the offer is made seriously and in good faith.[7] Offer the full amount by manager’s check. If refused, file the action and consign the money in court within the 30 days. In Butte, consignation on the 30th day was upheld.[2] In Baltazar, the Court treated filing plus consignation as the condition precedent.[7] Our guide to tender of payment and consignation when the other side refuses covers the court deposit.

Several redeemers. Each takes the sold share in proportion to his own share.[1]

Worked example

Facts. Siblings Ana, Ben, Carlo and Dina Reyes inherited a 1,200-square-meter lot in Lipa City. After an extrajudicial settlement, the TCT was issued in all four names, one-fourth each, undivided. On May 20, 2026, Carlo sold his one-fourth share to Mr. Victor Lim, a neighbor, for ₱1,800,000.

Notice. Carlo’s lawyer mailed each sibling a letter with a copy of the deed, received Monday, June 1, 2026. Excluding June 1, the last day to redeem is Wednesday, July 1, 2026.[2]

Who redeems. Ana and Ben want in; Dina does not. With equal shares, they split Carlo’s share: one-eighth each, ₱900,000 each.[1]

Tender and action. On June 22 they deliver two ₱900,000 manager’s checks to Mr. Lim with a written offer. He refuses, saying the lot is now worth more. On June 29 they file for legal redemption in Lipa City, consign ₱1,800,000 and annotate lis pendens.

Result to expect. A refusal based on current value is not a valid ground.[3] A winning judgment orders Mr. Lim to accept the price and convey the share, and may order an accounting of fruits, as in Butte.[2] Ana and Ben end with three-eighths each; Dina keeps one-fourth.

If they had waited. A first tender on July 2 would be late. Had only Mr. Lim sent the deed, his notice would not start the period,[2] but they should still act within 30 days.[7]

The buyer’s likely defenses

  • “You knew long ago.” The strongest defense. Answer with the date and form of any notice, and show you acted promptly.[7][8]
  • “I am already a co-owner.” If true, there is no redemption.[4]
  • “The co-ownership had ended.” A partition that assigned specific lots ends the co-ownership, and with it the co-owner status that Article 1620 requires.[1]
  • “Your tender was not serious.” Avoid this by tendering the full price, not a promise to pay.[7]
  • “You ratified the sale.” Receiving part of the proceeds can waive the right.[5]
  • “The price is higher than the deed says.” Be ready on the evidence of the true price.[3]

Step-by-step process

  1. Fix day zero (you, today). Record the date and form of every notice. Deadline: day 30 from the earliest reliable notice.
  2. Get the records (you, Registry of Deeds where the land lies, week one). Certified TCT and registered deed with the vendor’s affidavit. Check current fees with the Registry of Deeds.
  3. Confirm the right (you and counsel, week one). Apply the requirements table; choose Article 1620 or 1088.
  4. Raise the money (you, before day 20). Manager’s checks for your full proportionate price.
  5. Tender (you, to the buyer, by day 25). Deliver the checks with a written offer. Get a receipt or witness the refusal.
  6. File and consign if refused (counsel, court of the place where the land lies, before day 30). File the action for legal redemption and deposit the price with the clerk of court. Check current filing fees with the Office of the Clerk of Court.
  7. Protect the title (counsel, Registry of Deeds, right after filing). Annotate a notice of lis pendens; see our guide to what lis pendens does in a property dispute.

Which trial court takes the case can depend on how the action is framed and on the assessed value of the share. Have counsel confirm before filing; a wrong court costs days you do not have.

Barangay conciliation. If you and the buyer are individuals who actually live in the same city or municipality, a dispute within the lupon’s authority ordinarily cannot go to court without first passing through the barangay (RA 7160 Secs. 408 and 412(a)).[9] The law lets parties go directly to court where the action is coupled with a provisional remedy such as a preliminary injunction, or may otherwise be barred by the statute of limitations (Sec. 412(b)).[9] Whether the 30-day redemption window fits that second exception was not verified, and the Supreme Court treats the window as a condition precedent rather than a prescriptive period,[7] so do not rely on a barangay filing to stop the clock. Settle the route with counsel in week one.

Documents to prepare

  • Certified true copy of the TCT, with all annotations
  • The deed of sale, or a certified copy from the Registry of Deeds
  • The vendor’s affidavit of notice filed with the deed, if any
  • The notice you received, with envelope, registry receipt or courier tracking
  • Proof of co-ownership: deed of extrajudicial settlement, birth certificates, prior title
  • Manager’s checks for the full redemption price
  • Your written offer to redeem and proof of delivery or refusal
  • Evidence of price if disputed: zonal value, comparable sales, appraisals

Common mistakes

  • Sending an “intent to redeem” letter and waiting. Without a tender and, if refused, a filing with consignation, the 30 days lapse.[7]
  • Counting from the buyer’s notice, or from registration. The rule is the seller’s written notice; counsel will still count conservatively.[2]
  • Tendering a partial amount. Offer your full proportionate price.
  • Accepting a share of the proceeds “for now.” That can ratify the sale.[5]
  • Fighting the sale as void. A co-owner may sell his own share; attack it only where there is a real ground, such as a minor’s share sold without court approval.[5]
  • Trying to redeem a sale to another co-owner. There is no right against a fellow co-owner.[4]

Frequently asked questions

How long does a co-owner have to redeem a share sold to an outsider?

Thirty days from written notice of the sale given by the selling co-owner, under Article 1623. The Supreme Court treats the period as a condition precedent to the right, not a prescriptive period. If the sale is of hereditary rights before the estate is partitioned, Article 1088 gives co-heirs one month from the seller’s written notice. Count from the day after you receive the notice.

Does verbal or informal knowledge of the sale start the 30 days?

Generally no. The Supreme Court held in Rama v. Spouses Nogra that mere actual knowledge is not enough unless coupled with laches. But in Baltazar v. Miguel it treated a co-owner who already had a copy of the deed as notified. Act within 30 days of learning about the sale to stay safe.

How much do I have to pay to redeem?

The price the buyer actually paid for the share, on the same terms. Market value today does not matter. If the price is grossly excessive, Article 1620 lets you pay only a reasonable price, but you must prove the excess with solid evidence, not a single realtor’s estimate. Two redeeming co-owners split the share in proportion to their own shares.

Do I need to deposit the money in court?

Tender the full price to the buyer first. If the buyer refuses, file the action for legal redemption and consign the price with the clerk of court within the 30 days. The Supreme Court in Baltazar v. Miguel treated filing coupled with consignation as the condition for a valid redemption when there is no accepted tender.

Can I redeem if my sibling sold to our cousin who is also a co-owner?

No. Legal redemption among co-owners works only against a sale to a third person, meaning someone who is not already a co-owner. In Fernandez v. Spouses Tarun the buyers were existing co-owners, so the others could not redeem. You may still ask for partition if you want out of the co-ownership.

What to do next

Your notice of intent to redeem

Address it to the buyer, copy to the seller. Include your name, TCT number and fractional share; the share sold (lot number, area, location, seller’s fraction, deed date and notarial details); the date and form of notice you received; a declaration that you redeem under Article 1620 (or 1088); and the amount and manager’s check numbers tendered. Ask for a deed of conveyance by a stated date. Sign, date and keep proof of delivery. The notice does not replace tender, and the conveyance must still be notarized and registered.
