In general, overstayers face an up to 10 year ban, however, on 13th May 2008, in a debate on the new HC231 overstayers restrictions, the Minister for Borders and Immigration, Liam Byrne, made this comment...
Quote:First, we will not automatically refuse applications from people applying to join their family permanently in the UK-that is to say, those applying for visas as a spouse, civil partner or unmarried or same-sex partner under paragraphs 281 or 295A of the immigration rules; a fiancée or proposed civil partner, as set out in paragraph 290 of the rules; a parent, grandparent or other dependent relative, as set out in paragraph 317; a person exercising rights of access to a child, as set out in paragraph 246; or a spouse, civil partner or unmarried or same-sex partner of a refugee or person with humanitarian protection, as set out in paragraphs 352A, 352AA, 352FA and 352FD. Following some of the comments made by hon. Members this evening, I will of course check to see whether we have cast the scope of those exceptions correctly, but my initial analysis is that that is where the discretion should apply.
Following that statement, the guidance to Entry Clearance Officers was revised, and you can read them here

Re. Paragraph 281 (a)
Quote:Spouses or civil partners of persons present and settled in the United Kingdom or being admitted on the same occasion for settlement
Requirements for leave to enter the United Kingdom with a view to settlement as the spouse or civil partner of a person present and settled in the United Kingdom or being admitted on the same occasion for settlement
281. The requirements to be met by a person seeking leave to enter the United Kingdom with a view to settlement as the spouse or civil partner of a person present and settled in the United Kingdom or who is on the same occasion being admitted for settlement are that:
(i) (a) the applicant is married to or the civil partner of a person present and settled in the United Kingdom or who is on the same occasion being admitted for settlement; or
(b)(i) the applicant is married to or the civil partner of a person who has a right of abode in the United Kingdom or indefinite leave to enter or remain in the United Kingdom and is on the same occasion seeking admission to the United Kingdom for the purposes of settlement and the parties were married or formed a civil partnership at least 4 years ago, since which time they have been living together outside the United Kingdom; and
(b)(ii) the applicant has sufficient knowledge of the English language and sufficient knowledge about life in the United Kingdom, unless he is under the age of 18 or aged 65 or over at the time he makes his application; and
(ii) the parties to the marriage or civil partnership have met; and
(iii) each of the parties intends to live permanently with the other as his or her spouse or civil partner and the marriage or civil partnership is subsisting; and
(iv) there will be adequate accommodation for the parties and any dependants without recourse to public funds in accommodation which they own or occupy exclusively; and
(v) the parties will be able to maintain themselves and any dependants adequately without recourse to public funds; and
(vi) the applicant holds a valid United Kingdom entry clearance for entry in this capacity.
For the purposes of this paragraph and paragraphs 282-289 a member of HM Forces serving overseas, or a permanent member of HM Diplomatic Service or a comparable UK-based staff member of the British Council on a tour of duty abroad, or a staff member of the Department for International Development who is a British Citizen or is settled in the United Kingdom, is to be regarded as present and settled in the United Kingdom
So it looks fairly good, but you obviously need to check with the High Commission (not "embassy") and fully disclose all the facts to them.
