Do you sell an old house in Soissons, a condominium apartment or a house with wooden frames and floors? Termites and merule are two different risks, but they raise the same question: what checks and information should be provided to the purchaser?
In Aisne, obligations are not those found in all departments. This file explains precisely the local rules, the clues to be examined and the useful steps before a sale.
Pedagogical diagram: An on-site inspection is necessary to identify the real nature of a disorder.
Termites are insects that feed on cellulosic matter, especially found in wood. Their activity can weaken building elements: floors, beams, oilworks or frames. Some damage remains discreet for a prolonged period, making an appreciation to the naked eye insufficient.
Merul is a lignivorous fungus that can develop in buildings with favourable moisture and ventilation conditions. It attacks wood and can seriously affect its mechanical strength. However, a mouldy odor or a moisture trace alone does not establish the presence of merule.
Control covers signs of termite activity, the presence of wood attacks and accessible parts of the building. The regulatory state responds to certified methodology and skills.
Targeted expertise may require technical inspection, identification of moisture causes and, if necessary, analysis. There is no « merule diagnosis » national compulsory at each sale.
Another xylophagous insect, wood rot different from merule or moisture-damaged materials can produce similar signs. Avoid making a diagnosis yourself on a single photograph: a specialist must identify the origin of the damage.
The regulation depends on the geographical areas defined by prefectural decree. It is not deduced from the age of the house, its architectural style, or its proximity to a watercourse.
The Prefecture of Aisne expressly states thatno termite orders exist in the department. For a sale to Soissons, the termite state is therefore not required solely under the prefectural decrees in force. This absence of obligation does not prove that a building is free of termites and does not obviate the obligation to report a known infestation.
Decree No SHRUC/RBDA/2025/1 concerns cadastral areas in 19 municipalities of Aisne, including Laon, Château-Thierry and Bourguignon-sous-Montbavin. The municipality of Soissons is not included. The decree therefore does not classify the whole department, nor the whole of the Soissonnais, as an area of presence of the risk of merule.
This information is based on the list of the decree of 30 October 2025 published in the collection of administrative acts and presented on the prefecture site. She must be verified at the date of sale, the orders can evolve. For property outside Soissons, particularly in a neighbouring municipality, the municipality should be controlled. and the parcel concerned.
Also note the following grade: absence of regulatory zoning does not mean possible absence of merule. If a fungus is present or if serious disorders are known, a technical examination and fair information of the purchaser is still necessary.
| Question | Response to Soissons on 01/11/2026 |
|---|---|
| Mandatory termite status at any sale? | No, in the absence of prefectural decree termites in the Aisne. |
| Does it appear in the merule zones of Order 2025? | No, the municipality does not appear among the 19 municipalities listed. |
| Is biological risk impossible? | No. Checks are still useful in the presence of indices, regardless of zoning. |
| Should we mention an infestation actually known? | Yes, it is necessary to avoid any concealment of a disorder likely to be decisive for the buyer. |
The termite diagnosis, officially « status of termites », is required when the built building is located in an area declared infested or likely to be infested in the short term by prefectural order. Both houses and private parts of condominium lots may be affected, depending on the perimeter.
It is performed by a diagnostic specialist who meets the requirements of certification, independence and assurance. In particular, the report indicates the parties visited, those who could not be visited and the elements where termite indices are found. It must be dated and signed.
Consult the prefecture or the town hall. Do not confuse the existence of termites in a department with a decree imposing a sales diagnosis.
If the regulatory status is necessary, check its corresponding certification and liability insurance.
Combles, basements, damp rooms and accessible wooden works may be included in the volumes examined. Report inaccessible locations.
In the regulated area, the termite state is valid for six months for sale. The professional specifies the limits of the examination.
In Soissons, an owner can request a search Voluntary in the presence of worrying evidence or as part of an in-depth study of the building. However, this approach must be distinguished from the general obligation of an order, which is currently non-existent in the department.
The discovery of termites also leads to declaration obligation in town hall. Depending on the circumstances and measures decided by the municipality, control may be necessary. This reporting obligation does not depend on the sale of the property.
At the national level, there is no systematic merule diagnosis imposed on every real estate sale. The legislation primarily provides for information to the purchaser on the risk of merule where a property is located in an area delimited by prefectural order.
In the communes and parcels of Aisne covered by the decree of 30 October 2025, this information must be annexed to the promise of sale or, failing that, to the authentic act. This does not mean that the order automatically requires a technical check to be carried out for merule for all buildings in the area.
A seller of a Soisson property is not subject to this specific obligation because of his address at Soissons. On the other hand, if he is aware of an infestation, prior treatment or serious disorder, he must transmit to the notary and the purchaser the elements available to him, without falsely stating that the absence of zoning guarantees the absence of fungus.
As soon as a merule is known in a built building, it must be declared in town hall by the occupant or, failing that, by the owner. For common parts of a condominium, this declaration is the responsibility of the co-owners' union. The regulations distinguish this statement from information due at a sale in a restricted area.
A search for merule requires skills adapted to wood pathologies, building and humidity. Ask the professional for the scope of his/her mission, his/her references, his/her insurance coverage and any analyses. Do not systematically equate the certification of a termite diagnosticist with a universal qualification allowing all fungus expertise.
There are city houses, old buildings and houses with wooden structures. These materials are not abnormal or necessarily fragile: they simply warrant appropriate attention when infiltration, persistent moisture or signs of degradation occur.
These clues alone do not prove the presence of termites or merule. Other insects, fungi or physical phenomena may be involved. A targeted inspection may clarify the causes before recommending repairs.
Repainting a wetland, covering a damaged floor or removing traces without understanding their origin may complicate the finding and sale. It is preferable to keep photographs, estimates, records and proof of treatment, and then have the premises examined under appropriate conditions.
The answer depends on the demand. For a regulatory status termites In an area where it is mandatory, choose a certified diagnostic expert for this field. For a suspicion of meruleInstead, look for demonstrated competence in wood pathology and analysis of moisture-related disorders.
Before ordering, ask for a written estimate of the parts or works examined, the method, access limits, expected results and any additional costs. A non-destructive inspection may not make it possible to conclude on a completely inaccessible volume: the professional must report these limits.

Consult the local directoryWood condition expertise is not automatically a processing mission. It may be appropriate to distinguish the professional responsible for drawing up a statement from the professional who will then propose work, in order to better assess the conclusions and estimates.
An owner who prepares a sale to Soissons must form a coherent file: diagnostics legally required for his property, documents relating to the work performed and information about known incidents. It is not necessary to exaggerate the dangers or minimize an anomaly that could influence the decision to purchase.
Invoices for processing, previous reports, declarations, guarantees, potential claims and work documents.
If a wood attack or fungus is suspected, seek an appropriate investigation before displaying the good as free of disorder.
Indicate the known elements, limits of controls performed and any zoning applicable to the property and its parcel.
Describe the documented work and actual characteristics; Avoid formulas that promise absolute absence of risk.
The seller must examine his private part, but also the useful documents of the union of co-owners when a disorder concerns a structure, a common cellar, floors or a collective building. A suspicion reported in the common parts must be returned to the trustee; the declaration of the presence of the merule, in this case, belongs to the union of the co-owners.
These issues can be combined with other obligations: asbestos, lead, Electricity, Statement of risks or Carrez law, depending on the accommodation. The search for termites or merule does not replace the diagnostics of the technical diagnostic file.
No, the Aisne is not the subject of a prefectural decree termites, according to the prefecture. Check that this situation has not changed at the time of the transaction.
The municipality of Soissons is not included in the list of 19 municipalities covered by the prefectural decree of 30 October 2025. This lack of ranking does not make it possible to conclude that there is no fungus in a given building.
No. In particular, the regulations require information on the risk of merule when a property is located in an area defined by prefectural order; it does not provide for a systematic technical inspection of merule for any sale.
Make the troubles known and identify their causes, preserve the useful documents, declare the presence in town hall according to the applicable rules and inform the notary in case of a sale plan.
It is prudent to provide relevant information on known disorders, treatments performed and their justification. The notary shall assess the necessary particulars in the acts.
No. These benefits have distinct objectives. Specific control of wood or moisture may be required if there is evidence to support this.
Yes, private lots or common parts may present disorders. Diagnosis obligations depend in particular on orders; information and declarations in condominiums follow special rules.
Six months for the termite state attached to a regulated sector sale. This period should not be transposed to voluntary merule expertise.
