Capital gains on earnings from sell of an investment property

[Thomas Witchard]

Hi, need some help.  My wife and I just sold an investment property we owned.  We were not aware that discussions for a 1031 exchange was supposed to happen prior to closing on the property.  This said the earnings from the sell will come in our name.  Is there anyway to do the 1031 exchange after the fact?  If not what can we do at this point to avoid capital gains?  Any help where this is concern would be much appreciated.
