In the United Kingdom, inheritance laws can be complex, and they may vary slightly depending on the specific region, as Scotland and Northern Ireland have some distinct differences from the rest of the UK. However, the basic principles remain largely similar. Here’s a general guide to sibling inheritance laws in the UK.

Siblings written into a will:

Regardless of who you are to the deceased, if you are outlined in a will, it is your right to inherit. This is just one reason why a will may be the bets option for probate. With a will you can outline exactly who, gets exactly what and include and remove people as you wish. Furthermore, you can distribute different assets to different people. For example you may want your Sister to inherit all your jewellery, whereas, without a will, the most entitled beneficiary would inherit regardless.

When are siblings entitled?:

When a person dies without leaving a will, the estate is distributed according to the laws of intestacy. In England and Wales, if there is no surviving spouse or civil partner, the estate is distributed to the closest relatives in a specific order. Siblings are included in this order, but it is dependant on each family tree if they or entitled or not. A spouse is always the most entitled, then children, then the deceased’s parents. If all of which have predeceased or do not exist the siblings will inherit. Multiple siblings will inherit equally.

Half-sibling inheritance rights:

In cases of intestacy (no will), half-siblings are only eligible claim on an estate if there are no surviving full siblings. This circumstance often arises in the absence of a will. Nevertheless, half-siblings can make a claim even if there are surviving full siblings. Whether this claim is accepted or not depends on the strength of the bond between the siblings.

The inheritance among siblings is significantly influenced by family dynamics when there is no will in place, determining the division of the estate.


Conflicts regarding inheritance can be a complex matter to handle. Such disputes commonly emerge when there is an underlying strained relationship between the siblings. For instance, if one sibling inherits a house while the other inherits only a car, disagreements might arise.

While personal resolution is possible in some cases, unfortunately, many disputes of this nature end up in court as civil cases, leading to a legal examination of the will. This legal process often incurs substantial costs and can adversely affect the parties involved. Hence, it is advisable to attempt to resolve conflicts amicably before resorting to litigation. Coping with expensive legal fees immediately after the passing of a family member is an additional burden no one wishes to endure.
