You do realize that NJ requires a separation period of at least 18 months before you can get a divorce on "no fault" grounds, right?
So, if you want to open this up, it will bring up the fact that your attorney (acting on your behalf) filed knowingly false sworn documents to the court, so therefore a criminal offense has occured? Do you want your previous divorce "nullified"? If so, that would make you a bigomist as you got married after that divorce.... but if you didn't meet the grounds for divorce (the 18 months) were you ever really divorced to begin with? And can you also be charged with bigomy?
Is this REALLY something you want to go back and do considering the possible ramifications it could bestow upon you?
"Separation is New Jersey's only no-fault ground for divorce. To qualify under this grounds, both the husband and wife must have lived separately, in different houses (not only different rooms) for a period of at least eighteen consecutive months. Moreover, in order to qualify for the no fault divorce, there must not be a reasonable expectation of reconciliation. N.J.S.A. 2A:34- 2A(d)."
Your attorney more than likely said you'd been separated for 2 years to meet the requirement to even get a divorce.
