I live in Texas. My sister passed away 6 months ago. She had 2 children, ages 15 & 18 years. Their father (my sister's ex-husband) has been taking care of the kids since my sister's death and living with the kids in their home (left to them in the will). He just informed me that he has not been living with them for the past several months and is now moving away permenatly to another city. The kids love this arrangement, what teenager wouldn't? To make matters worse, the 15 year old daughter is 3 months pregnant. My question is: is this abandonment on the part of the ex-husband and what are my legal rights as their aunt and trustee of their trusts? I told them I was going to sell the house and they would need to find a suitable place to live, or move in with relatives. They are furious with me at this point and refuse to cooperate. Pleas help!
