Commentary on the Sections: Part 1 Claim to acquire right Section 81: Claim notice: supplementary
142.Section 81 makes supplementary provisions in respect of the claim notice.  It provides that a claim notice is not to be considered invalid merely because of any inaccuracy in the details or form of the notice.  (That does not in itself prevent the landlord being able to dispute entitlement to the right to manage - if, for example, the notice incorrectly states that a property is eligible for the right, the landlord would be able to mount a challenge on the basis that the property is not eligible.)
143.Specific provision is made for circumstances where any member of the company at the time that the claim notice is served is not a qualifying tenant for the purposes of the right to manage.  Where that occurs, the claim notice would continue to be valid provided that the correct number of qualifying tenants were members of the company at the time the notice was served.  (As set out in section 79, that would be qualifying tenants who held at least half of the flats in the premises or, where there are only two qualifying tenants in the block, both of those tenants.)
144.There may only be one claim notice served for an individual block at any given time.  Where a notice is served, it is therefore not possible to serve a further notice while  the first one remains in force.  A claim notice could cease to be in force because, for example, the company withdraws it or because it is determined that the company is not entitled to take over the management of the premises.
