Strategic Dispute Consultancy and Pre-Litigation Support
When a dispute is affecting your business, property or organisation, take control before it escalates.
Cosil Solutions is a strategic dispute consultancy and accredited mediation practice supporting businesses, organisations and individuals before disputes become harder and more expensive to manage.
We examine the facts, documents, correspondence and process; organise the evidence; identify what is preventing progress; and help clients decide what should happen next.
Our work includes strategic dispute consultancy, pre-litigation preparation, independent complaints and reviews, and civil and commercial mediation. Where formal legal advice or representation is required, we work alongside or refer the client to an appropriately qualified solicitor.

When to contact Cosil Solutions
You may need support when:
- a contract, payment or commercial relationship has broken down;
- a property, housing or construction dispute is escalating;
- a complaint or internal review has stalled;
- the documents are extensive, disorganised or disputed;
- communication between the parties is no longer productive;
- you are preparing for negotiation, mediation, a tribunal or an Ombudsman; or
- you need to understand the matter before instructing a solicitor.
Early preparation does not guarantee settlement, but it can clarify the issues, protect important evidence and prevent avoidable steps.
What we do
Strategic dispute consultancy
We review what has happened, what the available information shows, what outcome is being sought and what is preventing progress. We then help the client develop a practical dispute strategy.
Pre-litigation support
We prepare documents, evidence, correspondence and chronology so that the client can make informed decisions before committing to formal proceedings or instructing a solicitor.
Independent complaints and reviews
We examine complaints, decisions and internal processes where an organisation requires experienced external scrutiny, clear findings and practical recommendations.
Civil and commercial mediation
When appointed as mediator, we act independently and impartially, helping the parties address the issues and explore whether an agreed outcome is possible.
Matters we support
- Commercial agreements, disputed payments and supplier performance
- Property, housing, leasehold and construction disputes
- Organisational complaints, governance concerns and stakeholder disagreements
- Partnership, professional relationship and multi-party disputes
- Tribunal, Ombudsman, negotiation and mediation preparation
- Cross-border matters involving parties, documents, property or business interests in different countries
Consultancy and mediation are different roles
When engaged as a dispute consultant, we support one client in understanding and preparing their position.
When appointed as mediator, we act independently and impartially for the process. We do not advise either party or decide the outcome.
The role, scope and professional boundaries are confirmed before work begins.

Client experience
“Insley took the lead on the entire process. She demonstrated clarity, initiative, and sound professional judgement throughout. It was clear that Insley was driving the resolution forward, balancing risk and time sensitivity with confidence and expertise. Her leadership and ability to navigate complex legal frameworks made a significant impact on the outcome of the case. A trusted and highly capable professional, I would welcome the opportunity to work with her again on any high-stakes or sensitive matter.”
Martin Olomofe MBA MRICS, Head of Property, London Borough of Camden
“Insley at Cosil Solutions provided me with support to complete a money claim against a large organisation following them causing significant damage to my home. Insley reviewed my claim, structured a proposal to amend and strengthen it, and responded in the time frame promised. Within hours the defendant offered an out of court settlement. Insley went above and beyond to help me negotiate a final satisfactory offer, which I accepted.”

Frequently asked questions
Can Cosil Solutions help before I instruct a solicitor?
Yes. We can review the factual background, organise the documents and evidence, clarify the issues in dispute and help you prepare a structured way forward.
Depending on the circumstances, the next step may involve direct negotiation, structured correspondence, mediation, a complaint process or referral to a solicitor. Where legal advice or representation is required, we will recommend involving an appropriately qualified solicitor.
Can a contract dispute be addressed without immediately starting court proceedings?
Many contract disputes can be addressed through early assessment, negotiation, structured correspondence or mediation before court proceedings are considered.
We help clients understand what has happened, identify the documents and evidence that matter, and prepare an informed dispute strategy.
Can early dispute preparation reduce professional costs?
Careful preparation can reduce duplication and avoid professional time being spent organising incomplete records or establishing a basic chronology.
We cannot guarantee a particular saving, but a clear case file, focused document set and properly defined dispute position can make negotiation, mediation and subsequent professional instructions more efficient.
Does Cosil Solutions support international or cross-border matters?
Yes. We can support the factual, documentary and communication aspects of disputes involving parties, documents, property or business interests in different countries.
Through the Grenada and Caribbean Practice, Cosil Solutions Limited supports businesses, institutions, investors, property owners and professional advisers with dispute preparation, stakeholder engagement and mediation. Where local legal advice or representation is required, the client should instruct an appropriately qualified attorney.
Discuss your matter
If a dispute is consuming management time, delaying payment, affecting a project or placing an important relationship at risk, tell us briefly what has happened.
