I got married in Nigeria 7 years ago.?
This is Not legal advice, just my thoughts. Take your Nigerian marriage documents to the court that handles divorce in your part of Texas to have it declared legal. Once it declares your marriage legal, you can divorce. Hire an attorney who can help you find out the requirements for divorce in Texas and if they have been met you can have your husband served in Canada with a divorce complaint. If he doesnt contest and defaults, your attorney can get the divorce granted. This is complicated, hire competent legal counsel. If you are planning to remarry you dont want to end up as a bigamist. It may also be that your marriage in Nigeria is not legal in the US (for example a traditional marriage) so its important to have a court declare whether its valid or not. Good luck.
