合同上写的是 assured shorthold tenancy（双方都签字了），但是实际上是房东和房客share房子 （lodger & resident landlord）。这种情况下，如果dispute，法官会按照签的合同来看，还是按实际发生的情况看？
感谢大侠指导。
网上找到这个说法供你参考
Generally one of the main signs of a tenancy is that the tenant has ‘exclusive occupation’ ie the right to keep everyone out of the property (in this case the tenant’s room), even the landlord. So if the door has a lock and the tenant is given a key, this will not be a tenancy if the landlord also has a key and regularly goes in from time to time, for example to do cleaning or to change the sheets. However if the landlord does not have a copy of the key and has not entered the room for a couple of years, then there will be a strong probability that the occupier will be a tenant.

CAB网站的说法
Most tenants who rent from a private landlord are assured shorthold tenants. You are likely to be an assured shorthold tenant if:
your tenancy started on or after 28 February 1997, and
you pay rent to a private landlord, and
you don’t share any accommodation with them.

谢谢成龙大哥。
这些文章说的是怎么界定应该使用的合同类型。
但是，假设100%肯定就是lodger。只不过当时签contract的时候用错了模版，用了 assured shorthold tenancy agreement (AST)。这种情况，如果有纠纷，法官会按照lodger来判还是 AST 呢？
不符合法律要求的合同，签了也没用，这就是为什么需要那么多律师的原因。
我找到这个，感觉法官应该按实际发生的情况来判定，而不是用错了的租约。呵呵。
