1- It is a religious obligation. Prophet Muhammad ( ) said, "It is not permissible for any Muslim who has something to will to stay for two nights without having his last will and testament written and kept ready with him." [Bukhari].
2- You can frequently save hundreds of thousands of pounds in inheritance tax - the inheritance tax rate is 40% and applies to all assets you own worth more than Pound 325,000 (with some exceptions).
3- Creating a legally binding will that states how your estate should be handled help prevent serious family disagreements.
4- You can save your inheritors tens of thousands of dollars in additional legal, court, and inheritance tax expenses (Pound 9,700 is the average cost of dying without a will, according to the mainstream will writer Minawill).
5- You can spare your inheritors and executors a great deal of time, stress, difficulty, and worry by explicitly defining who will be an executor, who will be the guardian of your children, and who will receive what. You may believe your wife or husband would settle matters for you, but what if a family member disputes this after you're gone? Clarity is usually the best option.
6- You don't want to leave something as important as the guardianship of your children up to the family courts, who may rule in favor of someone you wouldn't approve of.
7- If you are not legally married to your spouse (for instance, if you have performed a nikah), drafting a will ensures that your spouse will inherit something. It will also ensure that your spouse receives a portion of the family home, which she would not receive under intestate succession statutes.
8- Without a will, stepchildren, foster children, and other dependents who are not blood relatives will not inherit anything.
9- It is a valuable practice in and of itself to contemplate death properly. Additionally, you are administratively compelled to act. How will your executor ever locate the random bank account you opened with Pound 200?
10- As a Muslim, you can donate up to one-third of your fortune to a continuing charity (Sadaqah Jariyah) that will benefit you in the next life. In accordance with what Prophet Muhammad (saw) said, "When a person dies, his deeds come to an end except for three: Sadaqah Jariyah (a continuous charity), or knowledge from which benefit is gained, or a righteous child who prays for him." [Muslim].
