Questions
How is spousal maintenance determined in Texas?
Spousal maintenance depends on factors like the spouse's ability to meet needs, marriage duration, homemaker contributions, and misconduct. Texas limits awards to the shortest reasonable time.
What happens to retirement benefits during divorce?
Retirement benefits may be divided as community property. Characterization depends on when they accrued and whether they're separate or marital assets.
How are child support amounts calculated?
Texas uses 20% of net resources for one child, increasing 5% per child up to 40%. Courts may adjust for exceptional needs like education costs.
Can I modify custody or support agreements?
Yes, modifications are possible with substantial changes in income, marital status, or the child's needs through negotiation or litigation.
Does Texas recognize legal separation?
No, Texas does not recognize legal separation. Separated couples remain legally married, affecting property division and debts.
