Prenuptial agreement and mortgage — does it pay off?
Married couples in Czechia have joint marital property by default — everything acquired during marriage is shared. A prenuptial agreement (předmanželská smlouva) can change this. How does it affect mortgages?
Joint property vs. prenup
Default (no prenup): property bought during marriage is jointly owned 50/50, even if only one spouse paid. Mortgage is automatically joint.
With prenup: property is owned by whoever's name is on the deed. Mortgage can be in just one spouse's name.
How banks handle it
Without prenup, banks require both spouses to sign the mortgage, even if only one is on the title. Both are jointly liable. Income from both can be counted for DSTI/DTI.
With prenup, only the property-owning spouse is on the mortgage. Their income alone counts. The other spouse has no obligation.
When prenup helps
- One spouse has bad credit — keeping them off the mortgage avoids rejection
- One spouse runs a business — protects family home from business creditors
- Significant pre-marriage assets — protects against divorce splitting
- Second marriage with children — clearer inheritance
When prenup hurts mortgage qualification
If only one spouse is on mortgage, bank uses only their income — DSTI/DTI based on solo income. If you'd qualify on combined income but not solo, prenup means smaller mortgage.
FAQ
Can we change the prenup later?
Yes, prenup can be modified by mutual agreement at notary. But change doesn't retroactively affect existing mortgages or property — only future ones.
What if we marry without prenup, then sign one later?
That's called marriage agreement (manželská smlouva). Effective for future. For property already acquired before the agreement, joint ownership rules still apply.
Cost of prenup?
About 8,000–15,000 CZK at notary. Includes drafting and signing. One-time cost.
