Thats the idea... stress you out then you are more likely to cave in. So you have tried to be a grown up but it sounds like its beyond your fellow signatory. Make sure you have kept a record of all your pertinent conversations, dates etc. Put in writing that you are prepared to go to proffessional mediation, thus its clear you are being cooperative etc and actively seek to do so.
2 questions... firstly your solictor
...? What is their view.? Have they confirmed the verbal agreement
being witnessed. ? How clear was this suggestion, ie implied, passing chat etc
.
Secondly, clearlyPerceptions can be very different. Why did you agree with this particular person to buy it together.? Entering into such an agreement is crazy unless you have it tied up
or you are 100% confident in the Person and a neighbour wouldnt be a good choice....is their anything else behind the scenes going on. Why are they after the additional percentage of the land..i smell a rat...it doesnt add up with an issue of purely what work you are doing.
If they are unhappy with your potential forestry work then it makes zero difference whether you have 43/25/37 or whatever... there is more to this that is obvious. If you dont know what it is you need to find out..... know the oppposition.
Dont forget that you have a legal duty of care and thus if you have dangerous trees on your land , have such confirmed by a proffessional (in writing), then write to the otherside
to confirm this duty of care, give them a copy of the survey
and point out that they share this responsibility. Give them the oppurtunity to resolve the dangerous trees or put forward an alternative solution. Give them 28 days then go ahead...if in doubt of course talk to your solicitor.
I would also suggest you actually consider what your work would actually constitute... what would they actually do....sue you for maintaining the safety of the wood, coppicing... you dont sound as if you are causing damage persae.....
Lastly if you are saying her solicitor is effectively trying to negotiate an agreement that gives away part of your property in return for permission to work on maintainance i suggest you write to the legal ombudsman and make a complaint against the solicitor, it appears wholly unproffessional.....it really sounds as if this about access and boundary demarkation rather than what your doing in your wood.
