However, it's essential to consult with a legal professional in your jurisdiction to get accurate advice tailored to your specific situation.
In most places, bigamy (being married to two people at the same time) is illegal. If your husband is still in a de facto relationship with the mother of his children and has not legally dissolved that relationship, then he may be committing bigamy.
As for your legal stance, it will depend on the laws in your country or state and the specific circumstances of your situation. In many places, common-law or de facto relationships may have legal implications, including property rights, financial responsibilities, and potential rights to support or division of assets.
Given the complexity of the situation, it's essential to seek advice from a family law attorney who can review the specific details of your case and provide guidance on how to protect your rights and interests. They can help you understand your legal position, explore possible courses of action, and advise you on the best steps to take moving forward.
In the meantime, consider gathering any relevant documents or evidence related to the situation, and focus on taking care of yourself and your children during this challenging time. Remember that legal matters can be intricate, and seeking professional legal counsel is the best way to navigate them effectively.
