How so? By obtaining a signed document from a minor to do an illegal act does not override existing laws. Neither anything becomes legal if one gives another a permission to do contrary to law and that too with a malicious and ulterior motives.
One thing my father advised my mother to do at the time of a oral family arrangement (which was cancelled by my lawyer brother) was to pay property tax on one of my mother's inherited property in my name. The tax is still paid in my name for several years.
