Letter not picked up

[Ref]

I have a quick question. DH's agreement states that he must let BM know where SD is if she is not staying at our house for over 24 hours. This applies to BM too. Anyway, he sent his notice overnight and she did not answer the door for the UPS guy, thus she never recieved the notice.  Is DH ok because it was at her house by the time we left to go out of town, or does she actually have to have the letter in her hands?

You have proof from UPS that they attempted to deliver.  If she refuses to accept, that's HER problem.  You held up your end of the agreement  make damn sure you get proof from UPS that they attempted and she refused.  That's all you need.........

You attempted to notify...via writing... (however, if she has a phone and you didn't call her, it may bite you in the butt)....
