What is de facto separation?
In a de facto separation, both spouses retain their marital status but live at separate addresses. It is often a transitional stage before divorce or return to married life.
De facto separation is the situation in which spouses or cohabitants decide to no longer live together, without divorcing or terminating their legal cohabitation. The marriage continues, but daily life apart.
In a de facto separation, both spouses retain their marital status but live at separate addresses. It is often a transitional stage before divorce or return to married life.
The spouses establish their residence at separate addresses. This separation can be:
- Voluntary (mutual agreement)
- Unilateral (decision of one spouse)
During de facto separation, the legal obligations of marriage remain in force:
- Duty of fidelity
- Duty of assistance and support
- Tax solidarity and certain household debts
After 6 months of de facto separation (joint request) or 1 year (unilateral request), divorce based on irretrievable breakdown can be obtained on this ground alone.
- Secure the separate residence and its financial aspects
- Settle child custody and residence
- Set any spousal or child support
- Prepare any future divorce in the best conditions
Sarah Satti advises you on the most appropriate choice between de facto separation, legal separation and divorce, depending on your personal, financial and family situation.
