You ask about getting your deceased mother's medical records. I am not clear about why you want them, but my experience is that most often, people want a deceased person's
medical records because they suspect that something was not right about the care the deceased received. If that is the case, be prepared to pay a fee for the records. They may be quite extensive for a long hospitalization.
You can request records in writing from a hospital's medical records department. Professional photocopy services go into the records department, copy the records and charge you,the requesting party by the page. It can cost hundreds of dollars to copy records for a long hospital stay. Because of confidentiality laws, you will need something to prove that you have the right to see them. If you do not have written permission, seek the advice of an attorney. If your reason for wanting the records is that you think the treatment was below standard, find an attorney who specializes in cases involving what you are worried about. The attorney can request the records for the purpose of investigating a suspected problem with the care if she or he represents the family of the deceased.
