In March, the Chancellor said he'd look at Deeds of Variation — rewriting a Will after death, often to save tax. I thought he was only saying that to get at Ed Milliband (when Ed's father died, the Millibands did a Deed of Variation). They are now after information.
At Budget 2015 the government announced a review into the use of Deeds of Variation (DoV) for tax purposes. The government wants to work with stakeholders to review how DoV are used to ensure that they are not being abused.
