I suggest that a will in contemplation of marriage does not contemplate entry into a civil partnership, even though the parties might be the same. If that view is correct, then the civil partnership will have revoked the will.
Even if the civil partnership is converted to a marriage, notwithstanding the marriage being deemed to be backdated to the date of the civil partnership, I would be reluctant to suggest this also had the effect of reviving the will revoked upon entry into the civil partnership.
As suggested by Kevin Mullen, the safest (and most cost effective) way forward is probably to make new will(s).
