Family and Divorce

Grainne is a highly experienced divorce and family lawyer who represents married and unmarried medium-to-high-net-worth individuals going through separation or divorce. She also provides advice and assistance to those wishing to enter into nuptial agreements.

Many of Grainne’s cases involve an international element: overseas assets, pensions, property structures such as usufructs, employment, and parties who live abroad or wish to relocate to another jurisdiction.

Her clients include business professionals, those in the public eye, heads of international corporations, British nobility and ‘silver separators’.

Grainne also has an extensive network of financial advisors, wealth managers, pension experts, forensic accountants, tax experts, private investigators and lawyers in multiple jurisdictions who she frequently works alongside.

Grainne qualified as a solicitor in 2005. Prior to joining Keystone Law in 2023, she worked at the following firms:
