My question involves real estate located in the State of: Indiana
We recently purchased a house with about an acre of land. My husband an the neighbor's husband are friends. We did not have a survey done when we purchased the house, so were unsure of the exact property lines in the back parcel of land. The neighbors have their yard fenced in, but apparently did not have a survey done when they bought the house either. They recently had a survey done and we discovered that their back yard came about 35 feet past their fence in what we thought was "our backyard". The 35 feet of area was heavily over run with weeds and had an uprooted tree that had been left their forever and was infested with mice. My husband cut down a few small, weed-like trees(sassafras) before the survey took place and before we knew that was actually their property. In one instance the husband actually helped him. Now that the survey is done, the wife is threatening to sue us for cutting trees down on "her property". These trees were like weeds and the neighbor's husband said he was glad that they were cut down and he was happy as that would save him a lot of work, with the work we have already done.
They never said anything when we cleaned up the brush, or removed some of the weeds. Would her case hold up in court for something like this? The husband wants no part of what she is doing, but I doubt he will testify against his own wife if it came to it. Also when we moved in there was already a couple huge trees that had been previously cut down(not by us), that were still laying in lumbers.
I have tried talking to her, but she won't talk to me. I wanted to offer to replace the couple of sassafras trees that we actually did cut down before we knew that was there property, but I am afraid that is like admitting doing something wrong.
Any advice would be greatly appreciated.
