Shoosmiths employees have chosen Barnardo's as the firm's new national charity.
It aims to raise £60,000 for the popular children's charity between May 2013 and April 2014.
Also chosen by staff is the national law firm's 2014 to 2015 charity, Winston's Wish, the UK's leading childhood bereavement organisation.
Money raised for Barnardo's will support its work preventing child sexual exploitation and to help expand the services it provides in the Midlands.
Specifically, the £60,000 will help pay for two outreach workers to rescue and support victims of child abuse.
Barnardo's, founded in 1866 by Thomas Barnardo, is the largest UK provider of child sexual exploitation support services, and last year worked with almost 1,200 victims through 24 specialist services.
Corporate relationship manager Trina Gable said: "We're delighted to have been chosen as Shoosmiths' corporate charity partner, and we are very excited about working together over the next 12 months.
"Barnardo's transforms the lives of vulnerable children across the UK through projects, campaigning, and research expertise.
"As a leading children's charity, we work directly with more than 200,000 children, young people, and their families, every year, through 900 vital services."
Shoosmiths corporate responsibility director Nicola Ellen added: "Fundraising for Barnardo's will happen at all our offices, and from past experience I'm confident that we'll reach the £60,000 target quite easily.
"When it comes to charity fundraising, Shoosmiths' employees are enthusiastic, creative and dedicated. They'll once again rise to the challenge."
Fundraising will take place at Shoosmiths' offices in Basingstoke, Birmingham, Edinburgh, Manchester, Milton Keynes, Northampton, Nottingham, Reading and Southampton.
It will continue from May 2014 for Winston's Wish, the UK's largest provider of services to bereaved children, young people and their families. Demand for its services has increased 30%, and the £60,000 Shoosmiths aims to raise will fund two new 'family service practitioners'.
Founded 20-years-ago, it helps young people re-adjust to life after the death of a parent or sibling, and is recognised as the leading organisation in this field, with a helpline that supports around 3,500 families and professionals, benefiting an estimated 7,000 children every year.
