People should leave clear instructions about what should happen to their social media, computer games and other online accounts after their death, according to the Law Society.
Having a list of all your online accounts, such as email, banking, investments and social networking sites will make it easier for family members to piece together your digital legacy, adhere to your wishes and could save time and money.
Not making your digital legacy clear could mean important or sentimental material - such as photographs on social networks - is never recovered.
Experts recommend that an up-to-date list of accounts, rather than a collections of usernames and passwords, is enough to ensure an individual's wishes are carried out.
Gary Rycroft, a member of the Law Society Wills and Equity Committee said people should not assume family members know where to look online and to make details of their digital life absolutely clear.
Digital assets can also include music, films, email accounts and computer game characters.
