There are arguments for and against. The advice you have sought is
based upon a property held in joint names which yours is not
(unless the property is in joint names but the mortgage is in your sole
name). If this is the case hawaythelads is correct that your ex has no
immediate legal entitlement.
However, it is possible for your ex
to make a claim against the property under the Trusts of Land and
Appointment of Trustees Act 1996, Section 14 for a declaration as to her
interest in the property.
Such a claim rests on the evidence
from both parties – your word against hers. Your ex would have to explain
why, when you purchased the property, the property was placed in your sole
name. You may have insisted upon this or it may be that there was never
any intention that your ex was to have a beneficial entitlement to the
property.
There is one issue, at the time of purchase, could you
have afforded the
outgoings without financial assistance from your ex?
If not, there is an argument that the affordability of the property was
based upon joint incomes in which case there may be a claim. It
is possible to argue that had your ex not been living with you, you would
have taken in a lodger but this seems a little implausible.
As
with all of these types of matters, the cost of litigating this type of
matter is heavy. The loser in the proceedings will usually bear the costs
of the winner as well as their own. In your case, your ex is unlikely to
be able to satisfy such an order therefore you would retain your property
but you would have to pay your legal fees as you would be unlikely to
recover these from your ex.
If you did engage
solicitors and settled the matter, your ex
would be looking for a payment for herself and to cover her legal fees. As
such, it might be advisable to offer a without prejudice payment for your
ex to 'go away'- a nuisance payment if you like. You can phrase this as
"..£x available for acceptance within 14 days otherwise this money will be
used to fund further legal fees. If the offer is accepted at a later
stage, the payment will be net of fees incurred following the final day for
acceptance until such a point that no payment will be available."
Currently, your legal position is strong but it is easy to create grey
areas by constructing an argument that the property is jointly owned in
every way apart from in title. Your ex's impecunious position may be to
your benefit as she may not be able to fund a claim against you.
