What does 'Escrow Disbursement Account in Trust' mean?

My mom just received a check from Chase Home Finance, and it only says :

Chase Home Finance LLC
Escrow Dibursement Account in Trust
For Various Mortgagors

We dont know if we are supposed to cash it or what. Does someone know what it is??

Thanks!
Update: It does not come with a letter or anything explaining, that is what the check says.
