disabled senior caring for my 48 yr old disabled daughter and her 10 yr old autistic son. she is very ill in hospital need to get guardianship other

they are my dependents living with me. need guardianship of my grandson. also need to add a middle initial to my name.it was on my ny driver lic and i used it all my 71 years and on all my documents eg ss, disablity, employment etc. i lost my birth certificate when moved fro ny to nj wrote ny for a replacement. ny sent me a legal copy but it did not have my middle initial. the envelope it came in did have my middle initial. nj motor vehicle took my ny licence and issued my nj licence without it because it was not on the replacement birth certificate. i need that middle initial back since it would impact my guardianship of grandson and all my financial records. this is for starters i also want to make a will in nj and have my son given power of attorney. my daughter who only has disability income ,blind diabetic wheelchair, homebound would probably want to make a will too.
