Not sure if this is the right location but here goes.
I left Ex when DC1&2 were under 2.5yrs. He was abusive to me, financially abusive to us all and choose to have no contact with the children from then on. He had paid a total of £472 in maintenance over a 13yr period. He frequently left jobs etc with CSA found him, arrested his wages at one point so he moved again. Of the £472, £40 was made up of £5 postal orders sent when he was unemployed from the DWP.
He recently committed suicide. Today I received a letter stating he owed over £20k in maintenance. Of which £16k is owed to me.
If I don't make contact then they will pursue his estate for their share only.
What would you do? Do I upset his family (3DC's and a partner/parents) and pursue this for the DC's or just leave it be?
