Where a deceased person was immediately before his death beneficially entitled to a joint tenancy of any property, then, if F1... an application is made for an order under section 2 of this Act, the court for the purpose of facilitating the making of financial provision for the applicant under this Act may order that the deceased’s severable share of that property F2... shall, to such extent as appears to the court to be just in all the circumstances of the case, be treated for the purposes of this Act as part of the net estate of the deceased.

Where an order is made under subsection (1) the value of the deceased's severable share of the property concerned is taken for the purposes of this Act to be the value that the share would have had at the date of the hearing of the application for an order under section 2 had the share been severed immediately before the deceased's death, unless the court orders that the share is to be valued at a different date.

In determining the extent to which any severable share is to be treated as part of the net estate of the deceased by virtue of an order under subsection (1) above, the court shall have regard to any capital transfer tax payable in respect of that severable share.

Where an order is made under subsection (1) above, the provisions of this section shall not render any person liable for anything done by him before the order was made.

For the avoidance of doubt it is hereby declared that for the purposes of this section there may be a joint tenancy of a chose in action.
