People who want to draw up a will should ensure they employ someone whose business is regulated by law, a spokesperson from Help the Aged has said.
Helen Foster, the charity's head of wills and legacies, advised individuals to seek the advice of either a bank officer or solicitor specialising in probate work when looking to draft a will.
However, she added a home will-writing kit can be bought very cheaply and will-writers may be less expensive than solicitors.
Ms Foster commented: "It's better to pay to ensure a properly drawn-up will now than to leave your heirs with thousands of pounds of legal fees and the stress of sorting out an unclear or poorly drafted will."
She pointed out the cost of writing a will can vary according to its complexity and the choice of method.
Help the Aged recently welcomed news of government plans to measure nursing quality for compassion of care.
It stressed the importance of the link between patient dignity and quality of care.
