Ex husband died 2011 leaving alimony and child support in arrears . Attorney advised me not to make a claim and paid himself leaving me no money

Ex husband died 2011 with a will giving all possession to our daughter . I was owed child support and alimony that was in arrears . Attorney told me not to file creditor claim against estate because then no money for our daughter . And also the angle of how selfish a mother id be to do that . My claim was a priority claim I received nothing my attorney took not only probate fees but hourly fees . My daughter turns 18 in May and I believe that my attorney did not work in my best interest or my daughter what can be done before she turns 18 to make sure she got the inheritance she deserved
