Yn gynharach eleni sefydlodd Llywydd yr Is-adran Teulu, Syr Andrew Macfarlane, weithgorau i ystyried arferion a phrosesau mewn cyfraith gyhoeddus a phreifat, i geisio nodi meysydd i’w gwella o ran y modd y caiff achosion eu rheoli a’r modd o ymateb iddynt yn ystod, a chyn, y prosesau llys. Mae Cafcass Cymru yn aelod o’r ddau weithgor.  Yn gynnar ym mis Gorffennaf 2019 cyhoeddodd y Llywydd adroddiadau interim y ddau grŵp yn nodi cynigion ar gyfer diwygio.
Earlier this year the President of the Family Division, Sir Andrew Macfarlane, set up working groups to look at practices and processes in public and private law, to try and identify areas for improvement in how cases are managed and responded to during, and before, the court process. Cafcass Cymru is a member of both working groups. In early July 2019 the President published the interim reports of each group setting out proposals for reform.
