Hi, Welcome to JustAnswer, My name is Andrea and my goal is to provide you with Excellent Service
1. You asked if you had the right to share in his property and his business
If you and he are married to different people, then you and he are not husband and wife and if he died, you could share in his property only if he left you property or the business in his will. If he did not leave you anything in his will, then the only way that you could share in the property or the business is if either your name was on the property and business with his, or you could prove that it was through your efforts that he acquired the property or you helped him establish the business. The same rules would apply if you and he no longer lived together. You would have to show that he acquired the property or business through your help and your efforts.
2. You also asked if you could claim child support
If he is the father of your children and you no longer lived with him, he would have a legal obligation to support the children and yes, you could go after him for child support.
