BEFORE you do anything, please call a lawyer. Pay for an hour of the professional's time. It's so much easier to nip issues in the bud instead of letting an issue grow until it's overwhelming and very expensive to fix.
Many people call me or post on www.avvo.com questions about what they should do.
Over 95% of the time my answer is "consult with an attorney about the facts of your particular case".
I especially encourage people not from Texas or unmarried people to consult with an attorney BEFORE moving in or getting pregnant. Many people are under totally false impressions about the law.
You can actually save a lot of heart-ache and money by learning the law BEFORE making life altering decisions.
