More a fraud examination question relating to UK property: I own a 3 bedroom semi-detached property in Edgware, North London which is separated by the occupiers next door by a shared alleyway which is owned 50/50 with these people. My wife and I have been receiving numerous letters over the past 12 months commencing 31st May 2011, from two solicitors of the occupiers next door stating that our wheelie bin (measuring no more than 4feet high x 22inches x 22inches in area approximately), is causing these people quote  "SUBSTANTIAL INTERFERENCE" as they claim they are not able to get their vehicles into and out of their back garden through this shared alleyway, even sending us letters demanding us to give them an "undertaking" NOT to store anything in the side alleyway and after we refused to give them this, then going further by threatening costs (up to £23,096.00 if Court proceedings are issued!!!!), damages,an injunction and court action if we do not move this wheelie bin from the alleyway even though other residents, including the occupiers of the next door property themselves have put not only their wheelie bins but other materials too in the side alleyway that separates two properties and as such all residents in this borough are all guilty of NOT having "clean hands" and as such court action will be thrown out if it ever gets to court! Putting these facts to one side, the issue I am concerned about, is the solicitors firm, Lyons Davidson who are based in Bristol and who are acting for these occupiers next door, has even included an "incident date" on their letters to us and dating this as '30th June 2011', i.e. I am assuming this is a date they have 'cooked up' on their insurance claim form since our wheelie bin has always been in this shared alleyway since July 2001, i.e. over ten years now and also since the first day we moved into our property, well before even the occupiers themselves moved into the property next door, i.e. some 5 years later in 2006 and as such, this 'incident date must be fraudulent and false to say the very least! Furthermore we even received a "Particulars of Claim" from this solicitor which they have threatened to use against us in court, further adding that they would prefer 'mediation' instead however we had none of this nonsense and told them to go to court instead, copying the Court in too!  As such events have moved quickly and possibly beyond the control of this solicitor and now we are due to go to Barnet County Court on the 15th May 2012 over a wheelie bin!!! Bearing in mind however this 'incident date' and furthermore and possibly unsurprisingly, we have discovered that approximately three months prior to receiving these threatening letters, i.e. on the 8th February 2011, the occupier of the next door property set up two general commercial businesses including fleet management from his residential property (something we found out last week after doing on-line checks on his name and address when this information possibly just went live on the internet), we have noted these key facts have been omitted from this 'Particulars of Claim' and the local council in Barnet was not even aware of any business operating from that address, something which we have now made them aware off and which they are now investigating separately! Bearing in mind all these points, particularly the solicitor not disclosing some critical information on their 'Particulars of Claim' they filed with the Court, i.e their "incident date" and the fact that their client has set up a commercial business from his home address with an attempt to use this shared alleyway which we also co-own to run his fleet vehicles over WITHOUT consulting me, the neighbours or the council or possibly even HMRC for the collection of any business rates that may be due), would this likely indicate an intent on the part of the occupier next door and possibly with the collusion and connivance of his solicitor Lyons Davidson of Bristol, to defraud us on our property title by denying us the enjoyment of our land (by giving them an "undertaking" as outlined above) and/or even his insurance company (assuming he may have a business interruption clause included in his policy where he may be claiming ingress-egress is being blocked by a wheelie bin or even exaggerating this claim), sending these threatening letters and mentioning Court action for even further leverage and credibility however then when the action really did end up in Court then deciding to opt for non-disclosure of key material information to the Courts, i.e. an incident date of '30th June 2011' and the fact that he has business interests with the neighbour's half of the side alleyway by putting it to use for fleet management and general commercial use and as such this in itself may be an issue with regards XXXXX XXXXX of Court, perverting the course of justice and so on and as such this may be something that the Court may wish to follow-up on, possibly by issuing civil and/or criminal proceedings against this occupier of the property next door? Sorry if the description was long however any feedback on any, or ideally all, of the points raised above would be much appreciated.
