Over the coming years, there is going to be a massive transfer in wealth between generations. While the majority of people don’t have wills and their estates will therefore be transferred in accordance with the default rules, a large minority do have wills and expect those wills to be honoured. The problem? DIY wills are vastly more likely to lead to will challenges.
If there is anything unusual about your will, you run the risk of having someone sue over it. Left an unequal amount to each child? Left out a spouse? Left nothing to your kids in favour of your new partner? Are there concerns about your capacity? Did you change your will to cut out someone who was in it before in favour of someone else? Anything the slightest bit out of the ordinary leaves wiggle room for someone who would be interested in challenging the will; having done a DIY will (a kit, or an online preparation service, or even a handwritten will) makes it far easier. A lawyer who does wills on a regular basis will have taken careful notes about your reasons, and if someone sues, this can help defend against them. Even if no one sues, losing out on valuable advice can cost your estate far more than you would have saved by not going to a lawyer.
I’ve said it before, and I’ll keep saying it: Get a will, and get it from a professional.
