Brian S. Loughmiller, a family lawyer in McKinney, answers:
The Texas Family Code provides for spousal maintenance post-divorce under certain circumstances. The amount and duration of support is dictated by a number of factors, including length of marriage and income of the paying spouse. Spousal maintenance is calculated at 20% of the gross earnings of the paying spouse, not to exceed $5,000 per month. An eligible spouse married less than 20 years may receive up to five years of spousal maintenance. A spouse married longer than 20 years but less than 30 years may receive up to seven years of maintenance. Marriages in excess of 30 years may entitle a spouse to 10 years of support.
