If, during the period of three years beginning with the day on which a grant is made under section 57 towards the repair or maintenance or upkeep of any property ("the grant property"), the grantee disposes of the interest held by him in the property on that day or any part of that interest, by way of sale or exchange or lease for a term of not less than 21 years, the local authority may recover the amount of the grant, or such part of it as they think fit, from the grantee in any court of competent jurisdiction.
If the grantee gives the whole of that interest to any person (whether directly or indirectly, but otherwise than by will) subsection (1) shall have effect as if the donee were the grantee.
If the grantee gives part of that interest to any person (whether directly or indirectly, but otherwise than by will) subsection (1) shall have effect as if any disposal or part disposal of that interest by the donee were a disposal by the grantee.
If any condition imposed on the making of a grant to which this section applies is contravened or not complied with, the grantor may recover the amount of the grant, or such part of it as he thinks fit, from the grantee.
Nothing in this section entitles a grantor to recover amounts in the aggregate exceeding the amount of the grant (for example by virtue of a breach of more than one condition or disposals of several parts of an interest in the grant property).
