Elder care lawyer may delay grandma's discharge from rehab over guardianship. What do you think?

I'm still dealing with an elder care lawyer to gain guardianship to handle my grandmother's finances when she gets out. Upon talking to them last week they want to delay her discharge while they are getting two doctors to testify that she is non compliant to do anything due to her condition. They have one on board but another hasn't done it ever, hence they will find another doctor to visit and get some background before going to the court. If that's the case that gives me more time to work on the house but what the lawyer told me makes sense. What do you all think are they right or not??!!
