Ever Pull Existing Corners?

Is it ever OK to pull existing pins?  The voices in my head are screaming NOOOO!!!!!!

 

But here is the situation.  A number of parcels are stacked northward on the west side of a north-south road.  Lead-ins come up the back of the parcels to a POB which then describes a square perimeter. The frontages vary. All parcels close.  All parcels are more or less contiguous ( gaps/overlaps less than 0.15'). There is one exception - the parcel I am surveying.  It falls to far to the south by 2.2'.  This creates an overlap of 2.2' on the south and a gap of 2.2' on the north.  This gap/overlap has been confirmed in a survey by another.

 

Now here is the problem.  All 4 corners were staked by the previous 20 year old survey.  The current owner is selling and wants to clean up the "conflict".  My advice is simple...concede the overlap, claim your full width and the gap.  I write a new legal and set new corners.  Then we'll get an attorney to prepare a correction deed.  Problem solved...no overlap....no gap...and everybody has their full frontage/area.

 

To prevent future confusion, I wonder if I should pull the old corners.  Feels wrong, but this is not a case where I am indescriminately pulling a corner just b/c I don't like it.  This is done after advising the client and at his direction.

 

Never done this before. What do you think?
