Reasoned offer from the insurer: what is it and what can you do if you disagree?

Received a reasoned offer after a traffic accident in Spain? Learn what it should contain, how to review the compensation and what to do if you disagree.

VMG Servicios Jurídicos infographic about a reasoned offer from an insurer after a traffic accident in Spain and what to do if you disagree with the compensation.

Direct answer

A reasoned offer is the insurer’s formal compensation proposal when liability and the accident damage can be assessed. Receiving it does not force acceptance. If you disagree, Article 7 of RDL 8/2004 provides specific supplementary expert-evidence options, rights and time limits before the next route is chosen.

Who this guide is for

People injured or otherwise affected by a road traffic accident in Spain who have received a reasoned offer or reasoned response and need to assess whether the valuation is properly supported.

Documents and checks

  • The prior claim sent to the insurer and evidence of receipt.
  • The reasoned offer or reasoned response received.
  • Medical reports, diagnostic tests and rehabilitation records.
  • Evidence of expenses, loss of earnings and property damage where applicable.
  • Any supplementary expert reports.

Recommended process

  1. 1.Review liability, the breakdown and the evidence supporting the offer or response.
  2. 2.Compare the valuation against the medical and financial evidence.
  3. 3.Identify omitted, undervalued or disputed heads of loss.
  4. 4.If the reasoned offer is disputed, consider supplementary expert evidence. The injured person may request a report from the Institute of Legal Medicine and Forensic Sciences even without the insurer’s agreement and at the insurer’s cost, subject to Article 7.
  5. 5.Where a supplementary expert report is delivered, check the new reasoned offer that the insurer must make within the statutory one-month period from delivery.
  6. 6.If the damage still cannot be fully quantified, check that the reasoned response contains the legally required information and periodic updates on the claim.
  7. 7.Assess negotiation, an appropriate dispute-resolution method or court proceedings according to the stage and facts of the case.

After a road traffic accident in Spain, the insurer for the responsible party may send the injured person a formal proposal stating the amount it is prepared to pay as compensation. This document is commonly known as a reasoned offer (oferta motivada).

Receiving a reasoned offer does not mean the amount is necessarily correct or that you must accept it. Before making a decision, it is important to understand what has been included in the calculation, what may have been left out and what options are available if you disagree.

What is a reasoned offer?

A reasoned offer is the insurer’s formal compensation proposal after a traffic accident when liability is established and the damage can be quantified. The main rules are contained in Article 7 of Spain’s motor vehicle civil liability and insurance legislation.

Once the injured person submits a claim, the insurer generally has three months to issue a reasoned offer if liability and the amount of damage can be assessed. If a final valuation is not yet possible, the insurer must instead provide a reasoned response explaining why.

What should a reasoned offer contain?

It should not simply state one final figure. The insurer should provide enough detail for the injured person to understand how the proposed compensation has been calculated.

  • the compensation proposed for personal injury and property damage;
  • a separate assessment of different heads of loss where applicable;
  • the medical reports, documents and other material used to calculate the amount;
  • a sufficiently detailed breakdown so the injured person can assess whether to accept or challenge the offer.

Do you have to accept the insurer’s offer?

No. Receiving a reasoned offer does not oblige you to agree with the insurer’s valuation.

Before accepting, it is advisable to review not only the total amount but also how each part of the claim has been valued.

What should you check before accepting?

1. Recovery period and personal injury days. Check whether the treatment period and the impact of the injuries on daily life have been properly assessed.

2. Ongoing symptoms and permanent consequences. If pain, reduced mobility or other lasting effects remain after treatment, make sure they have been taken into account.

3. Medical evidence. Medical reports, diagnostic tests, rehabilitation records and treatment history can be crucial to the valuation.

4. Accident-related expenses. Depending on the case, this may include medical costs, travel expenses, rehabilitation and other expenditure caused by the accident.

5. Loss of earnings. If the injuries caused an economic loss or prevented you from working, the financial consequences should be reviewed.

6. Property damage. Damage to the vehicle and other property should be assessed separately from personal injury.

What if the amount seems too low?

It is usually more useful to identify which specific part of the insurer’s calculation may be incomplete or incorrect rather than simply rejecting the figure as too low.

  • the recovery period has been calculated incorrectly;
  • ongoing symptoms or permanent consequences have been omitted or undervalued;
  • the insurer disputes the link between certain injuries and the accident;
  • expenses or loss of earnings have not been included;
  • property damage has been undervalued.

The offer can then be compared against the medical, financial and other evidence available, and a properly supported request for a higher amount can be prepared where appropriate.

Can you receive the offered amount and still claim more?

A reasoned offer should not make payment of the proposed amount conditional on the injured person waiving future rights where a higher compensation may legally be due.

However, any document sent for signature should be reviewed carefully. Receiving a payment is not the same as signing a settlement, release or final agreement with additional legal consequences.

What is a reasoned response?

Sometimes the insurer cannot yet make a final valuation. For example, treatment may still be ongoing and the long-term effects of the injury may not yet be known. In those circumstances the insurer may issue a reasoned response explaining why a final offer cannot yet be made.

How long does the insurer have to respond?

As a general rule, once the injured person’s claim has been received, the insurer has three months to issue a reasoned offer or, where justified, a reasoned response.

For that reason, it is important to keep evidence showing when and how the original claim was submitted to the insurer.

What can you do if you disagree?

Depending on the circumstances, you may be able to submit further medical or financial evidence, obtain an independent assessment, send a further formal claim and continue negotiations with the insurer. If the dispute cannot be resolved, other legal remedies may also be considered, including court proceedings where appropriate.

A simple example

Imagine an insurer offers €4,500 after a road traffic accident. The figure alone does not tell you whether the offer is fair. You would need to review the treatment period, impact on daily life, any ongoing symptoms, medical evidence, accident-related expenses, loss of earnings and the insurer’s calculation method.

Only after reviewing those elements can you make an informed decision about whether to accept the offer or continue seeking a higher amount.

Frequently asked questions

Do I have to accept the first offer from the insurer? No. If you believe the valuation is incomplete or too low, it can be reviewed and challenged.

Does the insurer have to explain the calculation? Yes. A reasoned offer should contain enough information to understand the basis of the proposed compensation.

What if I am still receiving treatment? If the damage cannot yet be fully assessed, the insurer may issue a reasoned response and continue the valuation once the medical situation becomes clearer.

Can I claim more than the insurer offers? Yes, where the evidence supports a higher level of compensation.

Before accepting a reasoned offer, it is worth checking what has been included, what may have been omitted and whether the valuation matches the medical and financial evidence in your case.

Frequently asked questions

Do I have to accept the insurer’s first offer?

No. A reasoned offer may be reviewed and challenged. The law also requires the offer to state that payment is not conditional on waiving future actions where the compensation paid is lower than the amount legally due.

How long does the insurer generally have to respond?

Article 7 generally provides three months from receipt of the claim for a reasoned offer where liability and the damage amount are established, or a reasoned response in other cases.

Can I obtain an additional medical-legal assessment if I disagree?

Yes. Where the reasoned offer is disputed, the injured person may request a report from the Institute of Legal Medicine and Forensic Sciences without the insurer’s agreement and at the insurer’s cost. Other supplementary expert reports may also be requested without the insurer’s agreement, but at the injured person’s own cost.

What happens after a supplementary expert report?

A supplementary expert intervention requires the insurer to make a new reasoned offer within one month of delivery of the report, with the limitation-period effects set out in Article 7.

What if the injuries cannot yet be fully quantified?

The reasoned response must explain why. Where full quantification is not yet possible because of the course of recovery or another reason, it must contain the statutory information and the insurer must provide a reasoned update on the claim every two months from the response.
