consequences

[black84]

if someone slept with there 26 year old stepdaughter after being seperated from her mother for 6 years what are the legal consequenses if it were to get out.

If you mean legal consequences - nothing. You have not broken the law assuming she consented.

[Ethel]

To clarify, a man or woman (A) can never marry a woman or man (B), regardless of his or her age, if A had been married to that B's natural parent (C) and B lived with A and C as a family unit whilst B was under 18 years of age.

But there is no problem with them having consensual sex as adults.
See Table 30 here, with the sentence above it which states:

The remaining step-relatives can now marry provided they are over 21. Also, the younger person must not have been treated as a child of the older person's family and never, under the age of 18, lived under the same roof as the older person.

Who ever is guilty of this crime is obviously very very sick!! there should be a law on it! after all anyone sleeping with there daughter is classed as a pervert, and step daughter is just as bad in my book!!
