“You’re Remarrying? Hand Over the Dog.” — Court Rules the One Who Paid Gets to Keep the Pet

By ,

A Korean court has settled a dispute over a dog caught between a separating couple, making clear that animal registration does not transfer ownership — and that who paid for the pet at the outset is what matters most. Here are the key points.

Issue

When a couple in a de facto marriage jointly raised a dog that one of them originally purchased and the other later registered under animal protection law, who owns the dog after the relationship ends?

Facts

  • A and B began dating in 2014, moved in together in 2016, and held a wedding ceremony in September 2018 — but never filed a legal marriage registration, making theirs a de facto (common-law) marriage.
  • In November 2015, before they were living together, B purchased a male dog for ₩400,000 from someone met via social media. B paid the full price alone.
  • The couple raised the dog together during their cohabitation. In March 2017, A registered the dog under his name pursuant to the Animal Protection Act.
  • The relationship broke down in early 2023, the de facto marriage was dissolved in May 2023, and B has been caring for the dog ever since. B re-registered the dog under her own name in July 2024.
  • Upon hearing that B was remarrying, A contacted her demanding the dog back. When she refused, he filed suit seeking its return.
  • Both parties claimed the dog was their own pre-marital separate property.

Rule

  • Article 830 of the Civil Act, which governs separate property and property of uncertain ownership in marriage, applies by analogy to de facto marriages.
  • Under this framework, movable property acquired before the marriage — or during the marriage where the means of acquisition are clearly proven — belongs solely to the acquiring party, and that ownership is presumed to continue unless a transfer is demonstrated.
  • Animal registration under Korea’s animal registration system (introduced in 2014, mandatory for dogs aged two months or older) is a public health and animal welfare measure. It does not carry the legal effect of transferring ownership.

Analysis and Court Decision

  • The Daejeon District Court, Cheonan Branch (Judge Hyeon Seon-hye) ruled in favor of B on March 10, 2026, dismissing A’s claim.
  • The court found that B purchased the dog in full in November 2015, at a time when there was insufficient evidence that A and B had yet formed a de facto marital relationship. The dog was therefore B’s pre-marital separate property from the outset.
  • Although the couple raised the dog together, there was no evidence of any agreement to transfer or share ownership, so joint ownership could not be inferred from cohabitation alone.
  • A’s 2017 animal registration did not confer ownership on him. The registration system exists to protect animals and prevent loss or abandonment — not to record or effect changes in civil ownership.
  • The court also noted that A made no ownership claim for approximately 14 months after the separation, and only moved to reclaim the dog upon learning of B’s remarriage — a factor that weighed against him.

Key Takeaways

  • In de facto marriages, the separate property rules of the Civil Act apply by analogy: whoever acquired the asset before the relationship is presumed to remain its owner.
  • Animal registration is an administrative tool, not a property transfer mechanism. Registering a pet in your name does not make it yours in law.
  • Shared care of a pet during a relationship does not automatically convert it into jointly owned property without an explicit agreement.
  • Timing matters: who paid, when, and whether a marital or quasi-marital relationship existed at that point are the decisive questions.

Why This Matters

Pet ownership disputes are becoming an increasingly common feature of relationship breakdowns in Korea, and this ruling offers the clearest judicial guidance yet on how courts will approach them. For practitioners advising separating couples, the message is clear: document who purchased the animal, when, and with whose money. For policymakers, the case highlights a growing gap between the animal registration system’s administrative purpose and the expectations of pet owners who treat registration as proof of title.
