Paid the Mortgage for 5 Years, Put in ¥200K for Renovation — Walked Away With ¥300K From a ¥4M Apartment
The brutal math of pre-marital housing in Chinese divorce, and why "we're a family" is a dangerous financial assumption.
---
Here's a question I want you to answer honestly: if your spouse bought an apartment before marriage, put down the down payment, and registered it in their name — and then you spent the next five years paying the mortgage together — how much of that apartment do you think you own?
If your answer is "half," you're in the majority. And you're wrong.

The Math
Let me walk you through a real case.
Lin got married. Before the wedding, her spouse bought an apartment — down payment was his, the deed was in his name. Lin thought nothing of it. They were a family now.
For five years, they paid the mortgage together. ¥8,000 a month. Total joint mortgage payments: roughly ¥500,000.
Lin also put ¥200,000 into renovating the apartment. Her spouse said the renovation money was "borrowed" — so Lin helped pay that back too.
When the relationship ended, they separated. The apartment was worth about ¥4 million.
Lin received approximately ¥300,000 in compensation.

How ¥700,000 of Contributions Becomes ¥300,000
Under Article 78 of the Judicial Interpretation (I) of the Marriage and Family Part of China's Civil Code:
When one spouse purchases real estate before marriage, makes the down payment with personal funds, borrows the remainder, and the property is registered in that spouse's name — the property goes to the registered spouse upon divorce.
The non-registered spouse is entitled to compensation for:
- Half of the joint mortgage payments made during the marriage
- Half of the corresponding property appreciation attributable to those joint payments
Notice what's missing:
- The down payment appreciation: all belongs to the registered spouse
- Renovation costs: theoretically claimable as contributing to appreciation, but practically difficult to prove and often disputed
- Any notion of ownership: compensation is cash, not equity
The formula, simplified: you get back half of what you paid into the mortgage, plus half of the appreciation that portion generated. Not half the house. Not even close.

Why Renovation Money Is a Trap
Renovation objectively increases property value. In theory, the appreciation attributable to renovation should be included in compensation.
In practice, three problems arise:
- Causation: Was the property worth more because of the renovation, or because the market went up?
- Documentation: Did you keep receipts, contracts, and payment records?
- Acknowledgment: Will the registered spouse concede that the renovation added value?
Without contemporaneous evidence and cooperation, renovation contributions evaporate.

The International Comparison
In many common law jurisdictions, the family home is treated as a special asset — courts have broad discretion to redistribute value based on contributions, needs, and fairness, regardless of legal title.
China's approach is more rigid. Title follows registration. The non-owner's claim is limited to reimbursement for measurable financial contributions — not a share of the asset itself.
For expatriates and cross-border couples: if you're contributing to a mortgage on a property in China that you don't own, understand that your legal claim is far narrower than it would be in London, Sydney, or Vancouver. The protections you expect may not exist.

What to Do
- Get your name on the deed. Add it after marriage. This is the single most effective protection.
- Sign a prenuptial (or postnuptial) agreement. Specify ownership shares and mortgage responsibility ratios. A written agreement overrides the default rules.
- Keep records of every payment. Every mortgage transfer. Every renovation invoice. Label your transfers clearly.
- Don't treat "family" as a substitute for documentation. The legal system doesn't know you're a family. It knows who's on the deed and who has receipts.
