If there's no mortgage (or other form of legal charge) on the property you're free to add whoever you like onto the title register as being a co-owner of the property. (If there's any form of charge on the property, the permission of the lender would be required).
If the house was owned by you and your daughter as 'joint tenants', neither of you would own an individual share of the property. It would be your legal partnership which owned the whole of the property. If you were to die, your daughter would automatically own the whole of the house - and vice versa. (Neither of you could leave your 'share' of the house in a will, since neither of you would actually own an individual share).
If the house was owned by you and your daughter as 'tenants in common', you'd each own a specific share, which could be left to whoever you chose in your wills.
Lastly, if this question is related to the possibility of avoiding potential care home fees, this might be relevant:
