C.B.
Because your child is minor, there has to be a court order to compromise the claim. In other words, the court is looking out for your child and the court can order that the claim be compromised for the amount you are trying to settle for. If the court doesn't think the settlement is a good one for your child, the court can actually deny the request to compromise (settle) the claim.
In the order to compromise the claim, there needs to be language that the settlement proceeds are to be deposited to a blocked account with (name and address of bank) account number ________. It is further ordered that
no one can make any withdrawals from the account without a further order of the court.
If your lawyer is unable to help you with such a routine thing as opening up a blocked account, then you need another lawyer! This is civil law 101!
