The way you share ownership of jointly-held property really matters when making your Will, as shown in the recent case of Dunbabin & Ors v Dunbabin.

Angela and John Dunbabin, a married couple, had four sons, Michael, Timothy, Simon and Adam.

In 1983 the couple bought their family home jointly but there was no record stored of how their individual beneficial interests in the property were owned.

To determine the couple's type of ownership at the time of purchase, the court followed the well-established default position that Angela and John held the property as joint tenants as there was no evidence to contradict this.

The problems began when Angela and John both made Wills in 2003 and then made new Wills in 2008, in which a trust of the first-to-die's 'share' in the family home was created.

The terms can broadly be summarised so that the surviving spouse was entitled to live in the property until their death, following which the property would pass to the couple's four sons equally.

Angela died in December 2016 and their son Michael also died in December 2019. In November 2019 John made a new Will in which he directed that 75 per cent of his entire estate (including the family home) be left to Simon and 25 per cent to his other sons between them. John then died in April 2020.

The claim made by Timothy, Adam and Michael's widow and son to the court, was that Angela and John had in fact severed their joint tenancy before Angela's death. This would mean that John only owned half the property and could not pass 75 per cent of the whole property to Simon.

The court found that there was evidence provided by the Will writer that he had advised the couple about the need to sever a joint tenancy, and therefore concluded that the couple had severed the tenancy.

As a result, only 75 per cent of John's half of the property passed to Simon with the remainder of the property passing to the others.

The case illustrates the risk of a costly dispute arising if the correct advice is not given.
