handling underage in beneficiary lists

[Fernan Nava]

I have a contract to purchase a house in ca, this contract is almost 16 months old now. The person I contracted with is the executor and I am  using a sales agent. the house was left to 12 siblings and a grandson that lives with a step mother somewhere in the middle east. We have signed deeds from all the sibling so the purchase can go forward and they can get their share, unfortunately we have not been able to get a signed deed from the grandson, according to my agent because he is underage and second, there are  some custody issues with the step mom. M just putting it out there in case someone know something bout this situation that I do not, which would not be hard I do not know much.  thank you.
