What has to be seen is who has longer service at a station. For example, let us suppose that the wife is at Delhi for 5 years and the husband is at Lucknow for 3 years. Then, here, the wife has a longer service at her station. So, she can make an application for her transfer to Lucknow (i.e., at her husband’s station) so that they can be posted at the same station. However, if her request cannot be acceded to on the basis of non-availability of vacant post, then the husband (who is the spouse with lesser service at his station) may apply to the appropriate cadre authority for his transfer to Delhi, which is the place of posting of his wife.
I hope it is clear. You may see my reply on a similar question (Husband and wife posted at different stations both being government servants) which discusses the provisions of the relevant Office Memorandum of the DOPT on the issue of posting husband wife at the same station to the extent possible.
