The number of people accessing Legal Aid services for family law and domestic violence matters increased by 25 per cent over the past year.

Legal Aid lawyers worked on 12,636 family law matters over the past financial year - the highest annual number ever reported.

Kylie Beckhouse, director of family services at Legal Aid NSW, said the increase was "almost solely attributable" to new services being made available to dometic violence victims.

Ms Beckhouse said the increased uptake detailed in the Legal Aid NSW annual report was "a good news story".

"We are hoping more is invested in that space so we can provide those new services to people in regional NSW ... because we currently can't meet demand," Ms Beckhouse said.
