The cost of estate planning in the UK may vary depending on your personal and financial situation. According to my web search, basic fees for a UK-based estate plan, with no outside interests, could range between £500 and £3,000. This would include drafting the relevant paperwork, such as wills, powers of attorney, and trust deeds, as well as receiving expert counsel and registering the documents. It’s best to consult an advisor to determine he cost.
