From today (6 February), the fixed amount a surviving partner is entitled to when a spouse or civil partner dies without making a will, is rising from £250,000 to £270,000.
The fixed sum is known as the 'statutory legacy' and is designed to balance the interests of the surviving spouse with those of the deceased's children when no will is in place.
For the millions of adults in the UK without a will, the fixed inheritance sum increase is a safety net - but is no substitute for making sure the right people get what you want them to have after you die.
Here, we look at what the change means for your loved ones and how you can avoid the risks of your partner struggling to keep their home and lifestyle when you're gone.
The statutory legacy sum, which rises from today in England and Wales, applies to everything else.
So, if you have children, your spouse will get the first £270,000 and half of everything else. The other half will be divided equally between your children.
The statutory legacy sum was introduced in 2014 to modernise and simplify inheritance law.
It was designed to make it fairer and easier for those left behind when no will is in place to set out the deceased's wishes.
The fixed amount is meant to be updated at least every five years to catch up with inflation as measured by the Consumer Price Index (CPI).
It was last revised in October 2014, and this latest increase sees it rise 8% from £250,000 to £270,000.
While at first glance, extra inheritance for the remaining partner looks like their interests have been protected from erosion by inflation.
However, they could still be at risk of far worse - of losing their home and lifestyle.
For the remaining partner, with no will in place the statutory legacy sum means:
If you're married or in a civil partnership and don't have a will, the statutory legacy sum offers some protection, but there is none for unmarried couples living together without a will.
It doesn't matter how long you've been together - aside from any jointly owned property or accounts, your estate will go to your children.
If you don't have any children it will pass to other family members - so if your property is in your name alone, your partner could lose their home.
In all circumstances, whether married, in a civil partnership or cohabiting, the single most important action to take is to make sure you both have a valid and up-to-date will.
Making a will is the only way to ensure you leave money to the people you want to benefit, at the right time and in the way that suits you best.
Another step to take can be to balance out your assets so that they're not all in one name.
